My invention relates to a mixing device,

be very eflective in performing'the functions .for which it is intended. I V

With the foregoing and other objects in view, my invention consists inoertain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimedand illustrated in the ace companying drawing, in which Fig. 1 is a perspective view of a mixingtool constructed in accordance with my invention. Fig. 2 is a cross-section taken on the line v22 of Fig. 1. i e

Fig. 3 is a cross-section'similar to Fig. 2, andvs howing a modified form of the device. Fig. 4 is a cross-section similar to Figs. 2

and 3, and showing a further modified form of the mixing tool.

Referring by numerals to the accompanying drawings, which illustrate a practical embodiment of my invention,-10 designates a short handle that may be formed of wood, metal, hard rubber, or the like, and secured in any suitable manner to the lower end of said handle, preferably by means of a centrally arranged screw 11,-isa concavo convex disc 12, preferably of metal, that is arranged with its convex surface uppermost.

The marginal edge ofthis disc is sinuous, or provided with spaced indentations 13, and formed through the body of the disc, between its edge and the space covered by the handle 10, is a series of apertures 14, which'may be of any desired shape, although I prefer to form said apertures substantially oval, as illustrated. Y

I As illustrated inthe drawings the apertures 14 are disposed in radial alignment with those portions of the edge of disc 12 that prosqueeze upwardly through the aperture 14 so of said material or product will, as a resultof j ects outwardly between the indentations 13 and as a result of this arrangement the oleomargarine or other plastic product that is be i ing mixed .or crushed by the utensilwill .as to form elongated portions ofv uniform shape that will unite with each other andwith the adjacent portions of the body-of theprods 3 not in a plane above the disc and thereby produce a more thorough and uniform mix ture. ..Furthermore' by arranging the apertures in a radial alignment; with the outwardlyjprojecting portions of the sinuous edge the produce thatis engagedby the disc as the 7 same is pressed downwardly will be forced 5 inwardly toward a pointin line with the axis of the handle of the device and as a result said materialwill be compressed to a slight de- I gree and consequently increasing the travel of those portions ofthe product that pass through the apertures 14. Further, by arranging the apertures 14in staggered relation to the notches13, the product that passes, over the edges of the notches or indentations 13' as the device vis moved downwardly will move inwardly to unite with the product that passes through the openings 14before those portions .of the product that passthe edges of the disdbetweenfthe indentations unites with the product passing. through they open- 8.; ings, thereby renderinglthe vmixing opera:

tions more effective and capable of beingjac compli'shedvery' quickly and withlittleieff fort on the part of the operator.

v In the use of my improved m xing'device, the handle 10is manually engaged and disc 12 ispressedupward upon the material or product tobe mixed or crushed, and a portion the downward pressure which forces upward through the apertures 14, and repeated down ward pressing movements of the device. on the material or product will result in the very rapid and thorough mixture ofsaid material, V

or likewise a complete crushing or maceration of fruit, or the like. In the mixing of coloring matter with oleomargarine, the latter may be pressed with the tool, and by turning or rotating the tool, slightly at the same time it is pressed.

InFig. 3, I have shown the central portion of the disc provided with a depression or 7 sh ght;downwardjprdjecting portion 15, and
